Paleontologists, geologists, and other scientists divide Earth’s history into time periods. The largest time period is the supereon, and only applies to one unit of time, the Precambrian. Eons, eras, and periods are smaller units of geologic time.Eon, Long span of geologic time. In formal usage, eons are the longest portions of geologic time (eras are the second-longest). Three eons are recognized: the Phanerozoic Eon (dating from the present back to the beginning of the Cambrian Period), the Proterozoic Eon, and the Archean Eon.

These are the Hadean (4.6 billion to 4 billion years ago), the Archean (4 billion to 2.5 billion years ago), the Proterozoic (2.5 billion to 541 million years ago), and the Phanerozoic (541 million years ago to the present). Eons are the largest unit of geologic time. Epochs are the smallest unit of geologic time. A geologic epoch is divided further into eras.The oldest dated zircons dated from about 4.0 Ga — very early in Earth’s history.

Formal geologic time begins with the Archean Eon (4.0 billion to 2.5 billion years ago) and continues to the present day. Modern geologic time scales also include the Hadean Eon (4.6 billion to 4.0 billion years ago).The Earth has only been around for about one third of the time the universe has! Planet Earth formed. Earth's core and crust formed. The Earth's first oceans.Oxygen was absent in this eon as well. The crust of the Earth started cooling, which further led to the formation of the continents. The carbon dioxide was dissolved in the ocean water, surging its acidity. The end of the eon witnessed the formation of plate tectonics which shares similarities with the modern Earth. Water was found in liquid form.The Phanerozoic is subdivided into three eras, from oldest to youngest they are Paleozoic (“ancient life”), Mesozoic (“middle life”), and Cenozoic (“recent life”) and the remaining three chapter headings are on these three important eras.

Geologists start counting “geologic time” from Earth’s surface downward; that is, starting with younger surficial deposits and descending into older rocks and deeper time.
